y To all whomli't may concern.'

- Be it known that I, Tmionon voN BAUER, engineer, citizen of Germany, subjectof the King of Prussia and Emperor of Germany, residing at Berlin, WV'.' 15, in the ,Kingdom of Prussia and Empire of Germany, have invented certain Vnew and useful Improvements in Coke-Ovens, of which the following is a full, clear, and exact description. I v

-This invention relates to improvements in the manufacture of coke with or without the simultaneous recovery of the by-prod.

ucts.

All 'of the processes heretofore known, for the production of coke, and of coke ovens heretofore employed are subject to the drawback that on the one hand the heating power of the waste gases is only imperfectly utilized, while on the otlierhand the heating of the oven is not:l carried out to the best advantage.

In the systems heretofore usually employed, the flues or combustion chambers which are the nearest to the place of entry "of the gases usually consume the greater part thereof, with the result that t-oo.little gas is supplied to the combustion chambers which are situated at a greater distance,

which arrangement has naturally resulted in the unequal heating of the several chambers. Y.

The purpose of the present invention is to devise a method of uniformly heating the coke chambeis by means of the waste gases in such manner that these gases are caused to flow in equal volumes over the. whole of the coke battery as distinct from being supv:plied thereto in the form of a single current ff'oidijow. These separate and independent currents are supplied from above the retorts at which points they commingle with vcounter-currents of air that are supplied from under the retorts, which air currents are in .their passage to the comniingling point, preheated to a degree that will more readily and effectively facilitate combustion.- The arrangement for supplying the waste gases to the combustion chambers is such that the various currentsmay be united in groups of different volumes, and Vmeans are also provided to deflect the currents of thesev volumes in different directions whereby the distribution thereof may be manually controlled. And a further means is devised whereby the pressure of gas within the seving ducts a.

eral divisions is kept uniform iii cach. This method of supplying waste gases from above may be used iii coniiection.\vith ovens haviiig vertical chambers as well as with those having horizontal chambers. The supply pipes for feeding the waste gasesfto the combustion chambers may be disposed` to eitherh side of the coke oven and deliver centrally thereof, or they may be arranged centrally of the coke oven and distributed to the sides.

In the accompanying drawings,-Figiire 1 is a vertical sectional view of a ,series of ovens taken through the combustion chambers and gas supplying passages. Fig. 2 'is a transverse sectional view of Fig. 1, taken on the line N-M.

Referring to the drawings, whereinv like .wardly and at their terminals communicate with a common chamber a, and fromsaid .chamber the gas is delivered to the" com-4 bustion chamber m, by wayof communicat- The inclined tissage-ways are slightly different on'the rightr and left of Fig. 1, but in both types they are inclined downwardly and inwardly. Fol` Y equalizing the 'pressure of gas throughoutall parts of the common chamber a there is a by-pass p' in the Acentral dividin wall. And for manually regulating theidirection of How of the gases from the several supply. passage-ways b', c and d there are twov baille members s that are adapted to be moved along the common chamber a, and by this means serve to -deect the incoming flow of gases and direct the'same `either toward the central wall P or to lthe farther sides `thereof all according to which combustion chambers need regulation.

The retorts S and the manner of.supplyv ing the material thereto are of that type usually employed on coke ovens of this general character., and since they form no part of this invention need not be described here.v

The air for supporting combustion'of the gas within the chambers m is supplied thereto in this manner. Communicating with the under passages or arcli ways L are inlet ducts g through which the air passes into a common chamber h whence it enters through ducts h into a second common passage-way L (see Fig. 2), and from here it passes by ducts z' to a third chamber z, and thence upwardly to the channels disposed centrally of the walls c, In passing through the tortuous passage-way just described the air is gradually heated until when passing upwardly through the vchannels 7c it is brought to the maximum temperature at which period it is delivered through the outlets n located near-the top of the com-A bustion chambers, and at which points it meets or commingles with the gas entering through the ducts a from the chambers `a. Combustion being effected at this the uppermost point of the combustion chamber is by reason of the disposition ofthe inlet passages caused to burn downwardly which f fact is considered of much significance in coke ovens of this type. The products of combustion pass through the openings Z at the bottom of the chambers and vinto the byways m', and thence by way of the passage w out through. the common channel K.

Afine myself to this particular construction, but reserve the right to make such changes therein as will fall within the scope of the appended claim.

lVhat 1s claimed as new 1s,-- In combination with a series of retorts,

of combustion chambers in the side walls.

thereof, a gas distributing chamber located above said combustion chambers and communicating.therewith, a slidable bailie member in said gas distributing chamber for regulating the direction of flow of gas to the combustion chambers, a plurality of channels for supplying gas to said distributing chamber, and flues for conveyingvpreheated air to the combustion chambers. l

In witness whereof, I subscribe my signature, in presence of two witnesses.
